According to Symantec’s December State of Spam Report, which took 450 million inboxes worldwide into consideration, 72% of November emails were spam. Spammers and anti-spam programs fought hard in the ongoing battle of what gets to the user’s inbox. Throughout November, spammers employed tactics such as: Thanksgiving holiday captions in subject lines, advertisements of replica products, mass e-mail address collection using an animated snowball .gif image, “free” gift-cards from well-known companies, and seasonal lotto scams. Companies behind anti-spam products released updated versions of their products, shared information between each other, and once again employed more advanced filtering techniques.
